Title:
WATER-TEMPERATURE MEASURING DEVICE OF HEAT STORAGE TANK
Document Type and Number:
Japanese Patent JPH04194714
Kind Code:
A
Abstract:
PURPOSE:To enable water temperature to be measured at any fixed position without a tank by placing an expansion and contraction axis within a branch axis tube so that it can be slid and then providing a temperature sensor at a tip part of the expansion and contraction axis. CONSTITUTION:A tube-shaped branch axis 7 which can be rotated freely in horizontal and vertical directions for a main spindle 3 is provided at a tip part of the main axis 3 which is stored in a heat storage tank, at the same time an expansion and contraction axis 8 is provided within the branch axis tube so that it can be slid, and a temperature sensor 12 is provided at a tip part of the expansion and contraction axis 8. Then, the expansion and contraction axis 8 is contracted by a push-pull wire 11 and the branch axis 7 is inserted from a small hole 8 into a water tank 1 while it is folded. By sinking an operation pipe 6 downward up to a depth to be spread by rotating the branch axis 7 in vertical direction, the branch axis 7 is rotated in vertical direction and is spread. Then, the operation pipe 6 is moved upward, the main axis 3 is inserted into a hole for operation 4a, and then a fixed platen 4 is fixed at a hole 18. Then, expansion and contraction operation of the expansion and contraction axis 8 is performed by pushing out the wire 11 and the temperature sensor 1 is set at a specified position, thus enabling water temperature to be measured at any position.
